Solvent Recycling Applications

Parallel Synthesis is a technique widely used by researchers to speed the discovery of new compounds and screen for optimal process conditions. In the pharmaceutical industry, Parallel Synthesis speeds the discovery and development of potential drug candidates. Early practitioners coined the term `combinatorial chemistry` to describe the synthesis of large libraries with diverse chemical structures screened in mass for potential biological activity.

Chemical and Pharmaceutical Customized Environmental Solutions. Applying the right emission control equipment for the chemical and pharmaceutical industry requires a thorough knowledge and understanding of the process and system requirements, combined with the ability to provide custom solutions. Dürr MEGTEC offers a wide range of environmental solutions that include solvent recovery and distillation systems, thermal oxidizers, scrubbers, electrostatic precipitators, and fabric filters.

In waste water treatment systems our membranes are used with great success for the filtration of cleaning chemicals (surface treatment), for cell separation after biological processes, or for the recycling of paints and lacquers.

Purolite specialty adsorbents are solid copolymers with highly porous structures designed to adsorb and desorb a wide variety of complex molecules and structures in a range of environments. Purolite has two families of adsorbents, Macronet and PuroSorb, together they provide the widest range of adsorbents available.

Purolite has supplied ion exchange chelating resins to the hydrometallurgy industry for over 30 years. Such experience ensures that we understand our clients’ needs and have allowed us to custom configure our products to target specific elements of interest. Advanced ion exchange technology is used for the primary recovery of metal or the removal of impurities to increase the value and purity of the final product. Metals can be extracted from ores using several methods including hydrometallurgy, pyrometall...

We design solvent recyclers and washers to clean and maintain tools and filtration equipment used for the maintenance and construction of bridges, buildings, antennas, turbines and other structures requiring regular cleaning. Establish a new corporate image, clean old traces left by time or add new protective covering to a surface – whatever your need, we offer a complete range of equipment that gets the job done easily and effectively.

Alkali cellulose, MC, HEC, HPMC, CMC... Machine technology requirements in the cellulose industry are as varied as the products themselves. AVA, with its broad portfolio of horizontal and vertical mixers, drying mixers, and reactors, is ideally positioned in the cellulose market. Many references from our satisfied, established customers are proof of the efficiency of our machines.

We can manufacture a large variety of industrial washers specially designed for foundries. From the design concept of continuous-operation machines to the integration of automated and manual turntables, we are ready and able to meet your needs. We can also help with all of your applications: semi-automated, robotic or entirely automated. These various types of automated processes are only a few examples of the techniques that can be used in the design and manufacturing of solvent recycling equipment.

Solvent based inks in different colors and patterns are applied to paper, plastic, film and foil substrates. Finished products include all sorts of wrapping paper, wall covering, candy wrappers, flexible food packages, shrink labels, high quality magazines and many, many more. These industries employ ovens or dryers to remove the solvents from the finished product.

In customer-specific chemical processes, explosive and corrosive solvents are used to systematically change the stock characteristics of e.g. pulp or plastic which calls for appropriate measures to protect the machine as well as the environment. To meet such requirements, BELLMER KUFFERATH Machinery has adapted their screw presses` proven functional concept to suit special requirements, such as:

Importance of pH Measurement - Hydrometallurgical concentrating and refining applications require pH/ORP sensors to withstand aggressive environments while maintaining accurate
measurement. Processes such as cyanide leaching (e.g gold) and solvent extraction (e.g. copper, nickel, zinc) require pH and ORP to be at very specific values to yield the desired chemical species. pH may need to be controlled as precisely as ±0.05 for some processes. Even where this level of precision is needed, process environments are...

The key aspects of a caustic treating system pertain to the degree of contact between the caustic and hydrocarbon to facilitate the mass transfer. Increasing the specific surface area of contact in a two phase system necessarily creates a tight emulsion. The product hydrocarbon often contains entrained caustic, which is not easily recovered by a simple water wash followed by a separator drum. The spent caustic is often regenerated with sour-naphtha stream that is used to extract the disulfide oils into the...
